vBy;reference to Figures 6,, 7 and 8 it will be seen thanthe-slats areformed with their longer'iaces A mand.50;,paral1el. tTIfhese faces .48, and-5il of the slats-constitute the upperand lower faces of. the awning. :In addition,zthe facesr52 and 5.4 of each .slatiareparallel. cThese1atter'faces52and 54 are ,cu. .orrformedrat 1an1angle of forty-five degrees withjnzespectimthe:planeof the face .50 whereby thei slats -may: b e-reversed with respect to:each,

There are preferably-twenty- .rfibtaslatsdvofihe standard: awning when-assembled :onithe cross; barsim kin'g "a total "width of-the awning from encLto end of a pproximately 64 :inches. uThe-spacing between'the slats-ispreferiably -i;three-.eighths of an inch. Breferahlyfi the distance- :from" the upper end, such as -60, to the plane of the face 62 of the cross bar 2, as shown in Figure 2, is about 4%; inches, and with a length of 21 inches for each slat the distance of the lower face 64 of the lower cross bar 4, as shown in Figure 2, from the lower end 66 of the slat, is approximately 3 inches. When a 32% inch length slat is used this latter distance is 12 inches.

It will be apparent, of course, that many of these dimensions may be varied, except that the forty-five degree angularity of the faces 52va'nd 54 with respect to the faces 48 and 50 must be substantially preserved and the spacing between thev slats must be retained as substantially three eighths inch. However the thickness of the slatsand their lengths may be altered, and the number of slats in the overall length of the awning "may be changed. For instance, awnings ofvarious; lengths may be provided by extending the length of the cross slats 2 and 4 and continuing the'number of slats forming an awning. So also the length of the. slats may be any desired length, provided thelength is sufficient'in accordance with the diagram of Figure 9 to prevent the'rays of the sun as of December 21,.in a southern exposure, going above the line I08 'as shown in Figure 9..

Referring now in general to the broad aspects of. the invention, the'angularity of the bevelled slat faces, and'the spacing between .theslatsis preferably such as will, in addition to breaking up direct rainfall, preventthe penetration of'direct sun rays, 'for most. installations, while still permitting a maximum penetrationlo'fdiffused daylightand air throughthe structure In this 7 country,- shade awnings have their principalutility onother than north exposures, and many, if not most, urbanxareas are laidout with .the street's'extendin'g substantially north-south, and east-west. Accordingly shade awnings, for -.use on homes and like buildings placed in conformity with street divisions will have their principal applicability to substantially east, west, andsouth exposures. V I I Referring to Figures 9 to 14, a slat arrangement for a particular locality, for example, Chicagdplllinois; is illustrated. As is known, see'Fig'u're 12, the axis of rotation of the'earth maintains-a predetermined angle of inclination in respect to l the earths orbit around the sun. At a particular point on the earths surface, the angle of inclinationassumed by the sun during the day varies between thewinter and summer seasons, but i'sal ways maintained between predetermined limits. For example, .in Chicago, at high noon in midsummer the sun reaches an'angleof inclination of 71.5 degrees (Figure 13'), whereas at'high noon in midwinter an angle of inclinationof 24.5 degrees is reached (Figure 14). I I

Furthermore, in its rising and setting positions, in different months of the yearthe sunfis progressively shifted, rising and setting in'a more northerly position in the summermonths. Thus, referring to Figure 10, it will be seen that at'sun rise in summer the suns position is substantially as indicated by the line I00, slightly north of an easterly direction. As the seasonprogress'es the sunrise shifts southward and at midwinter rises juxtaposed inclined slat faces, and the space be tween the slats, being such as to just block out the sunrise rays in midsummer, as indicated by the line I00. As the season progresses, the setting position of the sun shifts toward the line I02, and it will be seen that at no time are the direct rays of the sun permitted to penetrate the structure. By this means penetration of direct sun rays is precluded at, alltirnes, while, permitting a maxqua'ntity'of diffused dayligl'i't an airto pass through the structure When the structure is used for a west exposure,

the slats are reversely arranged as indicated in =.Figure 11, the angle of inclination of the bevelled slat faces and the space therebetween again being such asto'just preclude the passage of the suns rays, atsunset 'insummer, at which time the sun at-a point substantially as indicated by the line I02. Similar1y,, at sunset, the setting 1 position shifts between summer and winter from a point'as indicated in Figure 11 by the line I04't0 the point as designated by the line. I06.

In using the structure of the present invention for an east exposure, the several slats are arranged as indicated in Figure 10, the angularityof the assumes the position indicated by the line I04. Accordingly, as in the case of the east exposure structure, transmission of direct rays will be at all times precluded; throughout the year. v

- Where the structure is employed for a southern exposure, as indicated in Figure 9, the slatsare arranged both as to length and inclination, to provide maximumefficiency. Thus, referring to Figure 9, the length of the=slats isi'preferably 'such'thatthe most slanting winter rays, indicated by'the line I08, are-blocked off from that portion 'ofthe windowor other-opening desired tobe covered, for example the upper window portion as shown. Furthermora theslats are arranged in either the east exposure positionor west *exposure position; depending upon the sheltering or-requirements for-the particular southern exposure opening to be sheltered. More particularly; in "m'anyinstances a given southern exposure maybe partly sheltered in the morning, asb trees or the like, in'which event the-slats will be arranged in the east exposure plan. -C'onverselyrif'the particular southern exposure to be sheltered is partly sheltered by-extraneous means from the afternoon sun, the'west exposure 'position for the slatsm'ay be employed. It'must be seen that in accordance with the invention the structure maybe adapted to the requirements for'the particular installation so as to provide against penetration of direct sunlight while maintaining amaximum transmission, of diffused daylight and air through the structure; and direct-transmission of driving rain is also precluded. e

It will thus be seen that by reason of the'mounting members and the springs 24, the rigid awning is maintained in erected position against the side of the frame members'of a door or any window or opening by the pull of the springs. These springs tend-to pull normallyupwardly on the latch members 34 so as to pull the studs 38 downwardly intothe narrower part of the. keyhole type slot :3 6, and in addition the springs also pull downwardly on the cross bar 2, through the intermediary ofthe-hooks l6 affixed thereto, whereby to snugly pull the upperedges 60 ofthe slats against 7 the vertical wall1-22-of the frame. To release the awnings; the finger pieces 40 are pulled downwardly-to align the studs 38 with the larger diam .eter; of ;the,keyhole slot 36- whereupon the straps may be removed from the frame members .22- and escapee slats :are identical in constructionand zwhen-gassembled to "the cross pieces,. as hereinbefore ;described, maybe assembled in reversed position, as shown in Figures 6 =and. 7,'.t0. accommodate either eastern or western exposure. g a t lift is apparent that many \widely Jdifferentrembodiments-ofthisinvention may-be made without departing from I the spirit 7 and r scope thereof and therefore it is not intended to 'be limited iexcept as indicated-inthe appendedclaims; Having thus described the invention,.what is claimed as'new-and desired to be secured by Letters Patent is: a, V
